invention relates more especially to what is known as a classification lamp for' use in railroad operation; that is to say a 1 -My invention has for its object the pronecessity of keeping in stock both right and lamp which'is adapted to be secured on the side-of a car or locomotive while in operation;

although it is apparent that improved lamp may be put to otheruses when'desi'red.

vision of a-lamp of comparatively simple construction and one which will serve, or be adapted for use on;either side of the car or locomotive, thus obviating thenecessity of constructing and having in stock both right and left lamps for the purpose of providing thenecessary indication or signal. 7 That is to say, my invention provides a lamp .which is reversible so that it may be used as a right or left lamp and at the same time provide the required signal regardless of its position.

As a result of my invention these signal or classification lamps can all be made from one pattern, thus obviating the necessity of using right and left patterns and also obviatingthe left hand repair parts.

The objects and advantages of my invention I will be readily comprehended from the detailed description of the drawings, wherein. Figure '1 is a side elevation of the lamp. 7 Figure 2 is a cross sectional view taken substantially on the line 2-2 of Figure 1 looking in the direction of the arrows.

Fignre3 is a vertical sectional View. Figure l. is a sectional plan view taken subtantially on the line 4- 1 of Figure 1.

' Figure 5 is a perspective view of one half In the particular exemplification of the invention, 10 isthe lamp casing which is usually of suitable sheet metal bent into cylindri'cal form, provided with a top or lid 11 -which is 'hingedly secured in place as at 12 to provide with a suitable hasp or latch mem berl3'a'dap'ted to snapinto engagement with a suitable pin or burr on the lamp side wall- The side wall 10 is provided with the usual handlelt for carrying the lamp when not in place; the handle being trunnioned in the side wall so as to permit it to swing toward one side of the lamp and at the same time permit the lamp to be secured to the usual lamp socket bracket provided on the end Walls of the car or locomotive.

The bottom of the lamp housing is provided with a supporting frame or bottom 15 which is preferably made intwosegmental sections,'one of which is shown in Figure 5. Eachsegmental section consists of a band 16, the outer perimeter whereof has the upstanding flange or wall '17 adapted to engage exteriorly with the side wall 10 of the lamp, while the inner perimeter is shown provided with an upstanding flange 18 to receive the removable bottom or cup portion 19 which is I provided with the usual standard fittings or socket element 20 for an electric bulb shown at 21. As the electric fittings form no part of my invention, a specific illustration and detailed description need not be entered into.

The lamp holding bottom member 19 is shown provided with an outwardly disposed annular rib as at 22 in Figure 3 which will prevent accidental removal of the member 19 from the opening provided by the segmental members 16 which constitute the'bottom supporting frame. e

The two segmental frame members 16 are substantially identical in construction, except that one of the frame members 16 is provided with the vertically and radially disposed supporting lug 23, the outer or base :side 24 whereof is provided with an extension 25 having laterally disposed flanges 26 adapted to slide into the usual socketed bracket at present in use. Bothsegmental frame members are provided with a hinge forming element 27 so arranged that the hinge member of one segment will lap the hinge member of the other in order that the openings therethrough may receive'a suitable hinge pin as at 28 in Figures 2 and 4; while the opposite ends of the segmental members are each provided with an outwardly disposed apertured lug 29 to receive a bolt 30 whereby the segmental frame members 16 are clamped together in closed position as shown in Figure 4. The composite supporting frame 15, in addition to being clamped about the lower end of the casing 10, is secured thereto and properly positioned thereon by slot and pin connections as shown in dotted lines at 31 in Figure 1; the pins being carried by the frame members and adapted to enter proper openings or slots in the lower end of the casing. r

The casing 10 is provided in itssides with two openings surrounded by the radially disposed shells or outwardly extendinghub por= tions 32, the openings and shells being arranged substantially at right angles to each other. The outer ends of the shells areshown each provided with an annular band 33 telescoping therein and arranged in snug fitting rel.ation;'the annular bands 33 being each provided with an outwardly disposed flange 34 in order to receive the split internally groovedclamp ring 35 for clamping the lens 36 in place. The split rings 35, after insertion about the peripheries of the lenses and the flanges 34, are held in firm clamping relation by means of a set-screw or small bolt as at 37 in Figure 1. By flanging the band 33 in the manner shown and described, I provide a. seat for the rubber or other suitable cushioning ring 38 for the lens.

The openings in the sides of the casing 10, namely about the inner ends of the shells 32, areeach provided with a glass holding slideway or frame 39, which is preferably of rectangular formation having the upper side removed or open to permit a proper colored glass 40 to he slid downwardly into the frame or slideway so as to completely cover the opening in the side of the casing. That is to say, the frame 39 may he in the nature of a channeledband formed to provide a bottom and two side walls with the channel or groove open at top to permit the glass 40 V to be easily slid downwardly into place and removed when desired. With this construction, it is apparent that my improved lamp may be changed from one side of a car or locomotive to the other and that the glass 40 may be replaced by a glass of a color adapted to provide the proper signal or indication. g

The blind or blank side of the casing 10 on the interior thereof is shown. provided with a pocket or frame 41 formed integral with the shell. The frame 41 is substantially rectangular in cross-section or of configuration matching the configuration of the glass 40; having a bottom andopenat top for the purpose of carrying the extra and replaced glass 40 when not in use. That is or pocket 41 may be provided with suitable partition strips or grooves to receive the marginal edges of the glass to hold the same against improper vibration.

The lamp may be composed of any suitable material such as aluminum, galvanized iron and the like, and the lenses 36 are of clear glass having the usual inner stepped faces; the desired color of light being provided by inserting the proper colored glass into the holding frames 39 arranged about the light emitting openings in the casing.

The segments of he bottom supporting frame 15' are each provided with a number of pins as at 42-, while the lower" end of the casing 10 on opposite sides is provided with a slot as shown at 31 in Figure 1. The pins 42 may be secured to the segmental frame member-16 either by screwing or otherwise; and one pin is intended to engage in a hole in the casing while the other engages in the slot 31; the holes and slots being arranged to adapt the lamp to be'mounted either on the right side or on the left side of a locomotive or car. In assembly, the pins are made to enter their respective holes and slots before the clamp screw or bolt 30 is applied.

In order to give sufficient rigidity to the casing, I show the upper and lower ends thereof provided with reenfor'cing bands 43, 43 welded or otherwise secured thereto.

With my improved construction, it 1s apparent that the lamp c'asingcan be made from 3- i a singe pattern, thus obviating the necessity for right and left patterns as is the case with the usual classification lamp at present in use.

While the lamp has been shown with an electric bulb, it is apparent that any method of illumination may be employed without-ne cessitating changes in the general construction; and while I believe the construction illustrated to be the simplest embodiment of my invention, certain modifications may be made without, however, departing from the spirit of my invention. What I claim is:

In a lamp of the character describedinvolving a main casing provided with a pair. of light emitting open1ngs,1n the s des thereof arranged substantially at right angles to. each other, a supporting frame disposed about the lower end of the casing and consisting of a pair of-ring segments hingedly connected together atone end while the other end of each segment is. adapted to]. receive a fastening bolt or screw, at least one of said segments having an outwardly extending socket en' agin' in means Whereb the "'osition e g .Y P

of the ring segments and said lug relative to the light emitting openings in the casing is 1 determined, the inner perimeters of the ring segments being each provided With an upstandingsemi-eircular flange, and a removable bottom provided with an upwardly extending flange having an outwardly disposed annular rib adapted to engage with the inner flanges-of sald ring segments.
